Title: Improvements in and relating to the manufacture of sheets by aggregation of flake materials
IPC: B28D1/32
Filed: 1918-02-25
Abstract: 153,612. British Thomson - Houston Co., (General Electric Co.). Feb. 25, 1918. Endless moving sieves.-Relates to apparatus of the kind provided with a foraminous or perforated travelling screen upon the surface of which the flakes are deposited by a current of air sucked through the apparatus. According to the invention, the screen travels upon a horizontal openwork rotating cylinder or drum within which the suction is created. The path of the current of air to the screen is obtained, for example, by a subsidiary screen so as to render more uniform the distribution of the flake or to prevent undue excess of material passing to the screen. The flalce-laden air is admitted together with ordinary air in a direction which brings the flakes first into the unseated portion of the moving screen, depositing the larger flakes first. The formation of mica flakes into a sheet proceeds continuously with the application of a fixative. The screen in the form of a continuous belt 21 of woven wire with 3/16 in. openings is carried by skeleton drums 22 and 23 with solid ends connected by flat metal bars. The drum 23 drives and is enclosed in a substantially airtight casing 29 into which the belt passes through narrow slits. The annular space between casing and drum is divided by spring rollers 33 and 34, the upper portion, and thus the interior of the drum, being connected with an exhauster, whilst the lower space 32 forms the chamber for the application of flakes to the belt; and has an air inlet 35 set at an angle to deflect the mica particles first to the right hand part of the moving belt. The supply of flakes is generated in a rotating drum 40, fed with mica from a hopper 53, provided with a loose fitting lid 54, preventing excessive entry of air. Mica in the drum on the latter being rotated, is shaken up and also carried up by and discharged from longitudinal paddles 50, and a quantity is thus drawn through the funnel-shaped outlet 52 mounted in a partition wall. Flakes pass into the chamber 55, and are carried down by the air entering at 57. In their passage along the inverted U conduit formed by the parts 56 and 63, the supply is regulated by a perforated rotating drum 60, part of which is shut off from the stream of flakes, by spring rollers 64, 65. Flakes are deposited in the left hand side of this drum, carried round and discharged on the right. A similar drum 66 regulates in the same way and has an air inlet opposite it to counteract excessive adherence of flakes. Thence flakes are carried to the chamber 32 by a perforated belt 71 moving in cylinders 72 and 73, the former of openwork construction and connected to the exhaust. The main assembling screen 21 after receiving the flake coating passes out of the casing 29 along a horizontal path into the atmosphere, but with its lower side over a partially exhausted chamber 83; it then passes between rollers 85, 86 coated with adhesive.

Abstract: 1,025,895. Amplifying circuits. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. Jan. 25, 1963 [Jan. 26, 1962], No. 3318/63. Heading H3W. A video signal generating device, e.g. a tape recorder, 6 is connected to a television receiver over a modulator 8 in which the output from the device 8 is modulated on to a carrier, and an isolating transformer 9. Alternatively, connection may be made over D.C.-blocking capacitors. The arrangement provides isolation of the signal generating device when the television receiver circuits are connected directly to the mains supply. As shown, the carrier generated in the modulator 8 is at the receiver intermediate frequency and it is fed to the screen-grid of the last I.F. amplifier 3 over R.C. coupling 11, 13; switches 14, 15 when closed respectively short-circuit the output from the device 6 and the signal input to the grid of the valve 3. The secondary of the transformer 9 is damped by a resistor 10 to provide the necessary band-width, while the modulator 8 may include pre-distorting circuits to compensate for the frequency response of the last I.F. transformer with the receiver. In a modification (Fig. 2, not shown) the transformer 9 feeds directly into a separate rectifier, the receiver containing a switch which selects the video output from this rectifier or the normal signal rectifier.

Abstract: 572,078. Supply meters. SHEPHERD, G. R. (Westinghouse Electric International Co.) March 3, 1944, No. 4004. [Class 37] In an induction meter a torque-adjusting means is combined with means for correcting the consequent change in phase displacement between the voltage and current fluxes. Fig. 1 shows a polyphase watt-hour meter having two driving discs 1, 3 mounted on a common shaft 5 and associated with similar electromagnets 7, 9. The electromagnet 7 comprises a core 11 having a voltage pole 13 divided into two sections 15, 17, which together with adjacent extensions 19, 21 of the core form the current poles. A voltage winding 23 surrounds the voltage pole 13 and current windings 25, 27 surround the current. poles. The usual quadrature loop 31 surrounds the voltage pole 13. In order that equal torques shall be applied to the discs 1, 3 when the electromagnets 7, 9 are similarly energized a torque adjustment plate 35 is positioned for movement beneath the voltage pole' 13 in a recess in the base 29 of the electromagnet 7, adjustment being effected by a screw 37. This adjustment at the same time causes an alteration in the phase difference between the voltage and current fluxes. In order to neutralize this a conductive member 39 is employed for lagging either or both of the voltage and current fluxes. This may be in the form of an auxiliary quadrature loop arranged to move across the face of the voltage pole in accordance with the movement of the magnetic plate 35. As shown in Fig. 2 an angular bracket 41 is attached at one end to the loop 39 and at its other end to a lip 43 projecting from the magnetic plate 35. The loop 39 may be formed of copper or bronze or may be replaced by a continuous sheet of such material. Specifications 456,491 and 466,544 are referred to.
